Bodo Möller ea7150b070 The various hash #includes in rand_lcl.h *are* needed despite 
<openssl/evp.h> is now used (MD_DIGEST_LENGTH definitions!).
No need to include such headers directly in md_rand.c.

Bodo Möller e9ad0d2c31 Fix PRNG. 2001-07-10 10:49:34 +00:00
Dr. Stephen Henson 323f289c48 Change all calls to low level digest routines in the library and 
applications to use EVP. Add missing calls to HMAC_cleanup() and
don't assume HMAC_CTX can be copied using memcpy().

Note: this is almost identical to the patch submitted to openssl-dev
by Verdon Walker <VWalker@novell.com> except some redundant
EVP_add_digest_()/EVP_cleanup() calls were removed and some changes
made to avoid compiler warnings.

Richard Levitte 41d2a336ee e_os.h does not belong with the exported headers. Do not put it there 
and make all files the depend on it include it without prefixing it
with openssl/.

This means that all Makefiles will have $(TOP) as one of the include
directories.

Richard Levitte bc36ee6227 Use new-style system-id macros everywhere possible. I hope I haven't 
missed any.

This compiles and runs on Linux, and external applications have no
problems with it.  The definite test will be to build this on VMS.
 2001-02-20 08:13:47 +00:00
Richard Levitte cf1b7d9664 Make all configuration macros available for application by making 
sure they are available in opensslconf.h, by giving them names starting
with "OPENSSL_" to avoid conflicts with other packages and by making
sure e_os2.h will cover all platform-specific cases together with
opensslconf.h.

I've checked fairly well that nothing breaks with this (apart from
external software that will adapt if they have used something like
NO_KRB5), but I can't guarantee it completely, so a review of this
change would be a good thing.

Richard Levitte d309394447 Make sure that 'initialized' is zeroed as well when cleaning up. 2000-08-08 15:06:44 +00:00
Richard Levitte d6ade7422a Looks like Win32 builds do not define THREADS. However, they're still 
supporting threads, which means that th assertion is supperbly
dangerous, so make sure it's not compiled under Win32, period.

Richard Levitte a4125514f5 There's a deadlock when ssleay_rand_bytes is called the first time, since 
it wants to stir the pool using ssleay_rand_add.  This fix provides the
possibility to call ssleay_rand_add inside a locked state by simply telling
it not to do any locking through a static variable.  This isn't the most
elegant way one could do this, but it does retain thread safety during the
stirring process.

Ulf Möller 8ad7635ec9 Move RNG initialization to RAND_poll(), and shared definitions to 
rand_lcl.h

Richard Levitte 3b3bc455d0 That's it, I've seen questions about this one time too many for 
today.  Time to add extra info so the poor users know where to
go with their troubles.

Bodo Möller 2ace287dea Move Windows seeding functions into a separate file. 
They have nothing to do with the particular PRNG (md_rand.c).

Bodo Möller b841e0acd8 'entropy >= ENTROPY_NEEDED' should be evaluated while the 
variables are locked.
 2000-03-30 06:11:54 +00:00
Richard Levitte 7ae634de49 Since ssleay_rand_initialize() unlocks then locks CRYPTO_LOCK_RAND, 
it's a good thing if ssleay_rand_status() would do the corresponding
lock and unlock as everyone else...

and re-enable seeding with more data than read from DEVRANDOM -- just
don't pretend it contains entropy.

Ulf Möller eb952088f0 Precautions against using the PRNG uninitialized: RAND_bytes() now 
returns int (1 = ok, 0 = not seeded). New function RAND_add() is the
same as RAND_seed() but takes an estimate of the entropy as an additional
argument.

Andy Polyakov 9a1e34e5de MacOS updates. 1999-12-19 16:07:19 +00:00
Bodo Möller 62ac293801 Always hash the pid in the first iteration in ssleay_rand_bytes, 
don't try to detect fork()s by looking at getpid().
The reason is that threads sharing the same memory can have different
PIDs; it's inefficient to run RAND_seed each time a different thread
calls RAND_bytes.

Bodo Möller c1e744b912 Make md_rand.c more robust. 1999-10-26 14:49:12 +00:00
Bodo Möller 023c8d0b0a Use of DEVRANDOM must be #ifdef'ed (the #ifdef was commented out 
between SSLeay 0.8.1b and 0.9.0b with no apparent reason).
If we *want* an error when DEVRANDOM is not defined (it always is with
the current e_os.h) we should use #error.

Andy Polyakov 17f389bbbf Initial support for MacOS. 
This will soon be complemented with MacOS specific source code files and
INSTALL.MacOS.

I (Andy) have decided to get rid of a number of #include <sys/types.h>.
I've verified it's ok (both by examining /usr/include/*.h and compiling)
on a number of Unix platforms. Unfortunately I don't have Windows box
to verify this on. I really appreciate if somebody could try to compile
it and contact me a.s.a.p. in case a problem occurs.
